Hi,

Read an object from the file assign it to an Object class variable and use the getClass() method to get the class name, and compare it with required class name if equal continue your process, else continue reading another object.

Regards,
Rakesh

Hi,

I think, you should have all the objects present and it can be object hierarchy as well, and now while deserializing, it will construct the
entire object graph.

There are some questions and answers to serialization and deserialization, I came across

Hope this helps.
Thanks.
